I am looking for the descendants of their daughter, Ada M. Berger, born 25 aug 1893 at Three Rivers, St. Joseph County, Michigan. She married Guy Thomas Avery born 9 oct 1892 also at Three Rivers. Last known, they lived at 2200 travers lane, flossmoor, Illinois. Guy & Ada had one son, George Robert Avery, Born 28 november 1918, in Chicago. Guy was president of Acme Steel, and retired in 1959.
guy & ada were mentioned as helping to compile a family genealogy, which i am hoping to update.
